1 Claim.

' This invention relates to improvements in manifolding or record assemblies of the type employing long continuous record and transfer strips interleaved in transfer relation with each other so that inscriptions made upon the upper or original record strip will be transferred by the transfer strip or strips to the interleaved or copy record strips.-

It is.common to interleave blank forms with carbon sheets so that type impressions may appear-on all of the several forms or blanks in the set ;at one writing, but such interleaving is troublesome, as well as the arrangement of the blanks in accurate registration, on ordinary typewriting machines.

Even with machines built for such specific purpose, separation of the fan forms from the carbons is not readily accomplished and crocking or smudging often occurs.

It is an object of the present invention to provide a novel series of integral blanks, two, three, four or more, interleaved with continuous strips of carbon paper, the blanks being accurately adjusted and held, together with the carbons, in a manner completely precluding relative slip.

A further feature is in the provision of a multiple leaved strip or assembly of the class men-- tioned and of an improved construction that can be used in any standard typewriting machine with entire facility and removed and replaced without danger of disarrangement.

Another aim is to produce a manifold series of blanks, separable from succeeding series, but held against individual separation by an improved construction and arrangement until after inspection and approval.

These several important objects are accomplished by the novel combination and arrangement of parts hereinafter described and illusv trated in the accompanying drawing, forming a material part of this disclosure, and in which:

Fig. 1 is a perspective view of a series of blank and carbon sheets in strip formation of any desireddength as arranged in accordance with the invention. Fig. 2 is a plan view of two consecutive blanks arranged for manifolding, the uppermost blank being partially torn away.

Fig. 3 is a transverse sectional view, taken on line 33 of Fig. 2, and drawn to an enlarged scale. As shown in the drawing, the manifold pile consists of four ,blank record strips or sheets |0a-l'0bl0c and llld, all, or a portion, of which bear imprinted forms as indicated, but, which do not affect the invention, other than the forms are arranged in exact registration.

Interleaved between the blanks are carbon strips or sheets I la.l lb and I la, both the blanks and carbons being uniform in width and of continuous length.

These several sheets are firmly held by a row of stitches l2 adiacent one of their marginal edges and extending the entire length of the roll or fan-fold form in which they are supplied.

Adjacent the stitches is a row of perforations IS, the space therebeyond being occupied by the printed form. r

The several series of blanks are bent or folded into a zigzag supply pack or assembly along transverse rows of perforations Hi which serve eventually to permit ready separation from the continuous interleaved manifolding assembly of .a set of record and carbon leaves interleaved in transfer relation, after the typing has been done.

It is to be noted that the row of perforations I3 merge with or embody elongated slits or shear cuts l5 adjacent the cross perforations M, thus 'enabling a small section 16 of the margin con- ,taining the stitches to be easily removed by an operator and in order to avoid soiling the fingers in separating the series, thumb notches I! are cut in each of the carbon sheets or leaves and are longitudinally spaced along the assembly, prefer ably intermediate the opposite longitudinal edges of the carbon strips and at the upper edges of the respective carbon sheets or leaves. As shown, these openings or notches ll may be positioned substantially centrally of the upper edges of the carbon sheets and contiguous to and merging with the respective weakened severance lines M. By virtue of this arrangement the edges of the carbon sheets at these openings H are inset from the overlying and underlying adjacent edges of the record sheets, so as to provide selective grip formations. When a set of leaves is severed from the assembly along the weakened severance lines It these openings I! will be caused to open through the adjacent edges of the carbon leaves or sheets, thus completing the selective grip formations.

Thus it will be seen that after separation of the typed set of blanks, the uppermost sheet may be inspected and checked prior to grasping said blanks at the margin I6 and at the thumb 50 notches ll totear off said margin containing the stitches l2 and freeing the blanks or inscribed form sheets, the carbons however being held attached to the marginal strip at the comer under the shear cuts 15 in the blanks. The carbons are 55 imperforate at it. The inscribed record sheets may thus be quickly and easily severed from the longitudinal marginal binding along the respective severance lines it and at the same time stripped or separated from interleaved relation with the carbon sheet While certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined in the appended claim.

Having thus described my invention, what I- claim as new and desire to secure by Letters Patareasso said transverse severance lines to each said record unit so as to form a longitudinally disposed detachable binding margin for each said record strip at each said record unit, said binding margins of the respective record strips being relatively superposed, said record and transfer strips being attached together at said binding margins at each said record unit, each said transfer sheet of each record unit having a grip opening spaced inwardly from each of the opposite longitudinal transfer strip edges and adjoining the respective transfer strip severance lines whereby the respective transfer sheets have edges inset from the adjacent record sheet edges so as to provide a se- ,lective grip formation spaced from the binding *margin at each said record unit, said longitudinal severanc lines of the record strips having elorrgated on 5 adjacent to the respective transverse weakened severance lines and said transfer stn'p being unweakened corresponding to said longitudinal weakened severance lines of the record strips. i
